- I DISHWASHING APPARATUS *Filed March 21, 1958 s Sheets-Sheet 2Patented Aug. 13, 1940 UNITED STATES PATENT OFFICE I 9 Claims.

My invention relates to improvements, in dishwashing apparatus, anobject thereof being to supply a simple, durable and effective apparatusof such nature adapted to be readily applied to the hot and cold waterpipes leading to a sink and toprovide a spray either of clear water orsuds varying in temperature, as may be desired, from that of the waterinthe cold-water pipe to that of the water in the hot water pipe andvarying in pressure up to the maximum of that afforded by the water insaid pipes.

Another object of the invention is to provide an apparatus of thepresent nature, including a receptacle having a closed soap chamberadapted v to receive clear water and discharge soapy water.

through a single valve in one position thereof, such valve, in anotherposition, serving to shunt theclear water past said chamber and, inanother position, to arrest the flow of water and 30 drain said chamberunder atmospheric pressure.

A further feature of the invention resides in 30 ber in such manner thata relatively large quantity of water may be introduced into the chamberthrough the inlet before the admission of additional water issubstantially resisted by the pressure of air trapped in the upperportion of 35 said chamber. 4

Other objects of the invention reside in the novel combination andarrangement of parts and in the details of construction hereinafterillustrated and/or described. v

In the drawings, Fig. 1 is a front elevational view of a dishwashingapparatus embodying my invention, the same being shown as applied to hotand cold water pipes leading through the back board of a sink; Fig. 2 isa side elevational view of the structure shown in Fig. 1; Fig. 3 is asectional view, in detail, illustrating particularly the soap receptacleof the illustrated apparatus, said view being taken as on the line 33 ofFig. 2; Fig. 4 is a detail sectional view taken as on 50 the line 44 ofFig.2, said view showingpartic- 5 to the view of said construction shownin Fig. 3,

but with the valve body turned to a difierent position; Fig. 7 is anelevational view, in detail, of the valve plug illustrated in section inFigs. 3 to 6, incl., and Fig. 8 is a detail sectional view of the spraynozzle illustrated in elevation in Fig. 1 and 5 in perspective in Fig.2. Referring to the accompanying drawings in which similar referencecharacters are employed to designate similar parts throughout .theseveral views, it will be seen that the illustrated embodi- 10 ment ofmy invention includes a receptacle l0 mounted upon and connected withbranch feed pipes ll, l2, respectively coupled with hot water and coldwater feed pipes l3, [4, leading through the back board ii of a sink andsupplying water 15 to a combined hot and cold water faucet l6 having apivoting spout ll. The branch feed pipe l2 includes a control valve I8which is screwed into a T-coupling or adapter l9 interposed between theend of the cold water pipe l4 and the faucet 2 I6. Likewise, the branchfeed pipe ll includes a control valve screwed into a T-coupling oradapter similar tothe T-coupling l9, such valve being interposed betweenthe end of the hot water pipe l3 and the faucet [6. Each of said valvesI8, 20, has a lever 2i for opening and closing the same and forregulating the flow of water 'therethrough from its respective waterpipe.

A coupling 22 connects the branch 'feed pipes ll, l2, with a valvehousing 23 formed integrally v anchored in the body of the receptacle [0provide bearings for the ends of a. pivoting yoke 29 through which isfitted a threaded clamping screw 30 having a finger piece 3|. The innerend of this clamping screw 30 is received in a depression 32 formed inthe closure 24 axially thereof, said closure being removably clampedagainst the sealing gasket 21 by means of said clamping screw 33. Withthe closure 24 removed from the body of the receptacle l0, cakes orslabs of soap may be introduced from the .top into the soap chamber 33within said receptacle, but with said closure 24 clamped in place, thechamber 33 is tightly sealed at the upper portion. of the receptacle.

The valve casing 23 is formed with a horizontally disposed tapered bore34 and fitting this v bore is a correspondingly tapered valve plug 35,

branch feed pipes ll, 12,

thrust plug 31 is a compression spring 39 into the inner end of which isfitted a thrust head 40. This thrust head 40 and said valve plug 35 areformed with opposed depressions 41, 42, which receive opposite portionsof a thrust ball 43, the action of said compression spring 39, thrusthead 40 and thrust ball 43 being to maintain a tight fit between thevalve tuning of said valve plug. Secured to the small end of the taperedvalve plug 35 is a handle 44 for turning said plug. This handle 44 issecured to the plug 35 by means of a fastening screw 45 passing through'said handle and threaded into said plug, relative rotation betweenhandle and plug being precluded by means of a key-pin 46 accommodated atits inner end in a bore 41 in said plug 35 and at its outer end in abore 48 in said handle. The valve plug 35 has a diametrical bore 49therein and at one side thereof a circumierentially extending channel50. At the other side of said diametrical bore 49, said valve plug 35 isformed with a longitudinally extending channel 5|.

The valve casing 23 is formed with a feed port 52 into which thecoupling 22 is threaded. In line with said feed port and formed in thebottom of the receptacle 10 is an inlet port 53. Said feed port 52 andsaid inlet port 53 are brought into communication for conducting waterfrom the into the soap chamber 33 within the receptacle Ill. To thusbring said feed port 52 and inlet port 53 into communication, the valveplug 35 is turned into a suds position, wherein the diametrical bore 49in said plug registers with said feed port 52 and inlet port 53 (Fig.3). The said casing 23 is additionally formed with a delivery port 54into which the coupling member 55 of a spray tube 56 is threaded andsaid casing is further formed with an outlet port 51 in the bottom ofthe receptacle I9, said outlet port 51 and said delivery port 54 beingbrought into communication in the suds" position of the valve plug 35through the circumferentially extending channel 50 in said valve plug35. Issuing upwardly into the receptacle 10 from the outlet port 51 is atubular extension 58, which is closed at the top thereof, but formedplurality of perforaat its upper portion with a tions 59 bringing thechamber 33 within the receptacle I into communication with the bore ofsaid tubular extension 58. The inlet port 53 is disposed co-axially ofthe soap receptacle I0 and the inner wall surfaces of said receptacle,at the lower portion thereof, slope inwardly toward said inlet port 53in order that the cakes or slabs of soap contained within the receptaclechamber 33 will be directed, in gravitation, to the bottom of saidchamber into position immediately above or near said inlet port 53. Thetubular outlet extension 58 issues from the outlet port 51 at an angleto the axis of the soap receptacle l0 and occupies a position closelyadjacent to the sloping wall surface of said receptacle chamber, wherebythe pieces of soap within the receptacle are not interfered with by saidextension 58 in their descent in the receptacle chamber to positionabove the inlet port 53. With the valve plug 35 in the suds position, asshown plug 35 and' the tapered bore 34 ofthe valve casing 23, yet permitthe in Fig. 3, the water from one or both of the branch feed pipes .l I,12, under desired regulation, enters the soap chamber 33 where it issaponified and thence directed into the spray tube 55.

The circumferential channel 53 in the valve plug 35 brings the feed port52 into direct communication with the delivery port 54 in a clearposition of the valve plug 35, as best shown in Fig. 6. Functioning tothus bring said feed and delivery ports 52, 54, into communication, thechannel 59 in the valve plug 35 shunts the water fed from the branchfeed pipes ll, .12, into the spray tube 56 in order that such water willnot be subjected to the soap within the receptacle In addition to thesuds" and clear positions of the valve plug 35 previously noted, saidplug may be turned into a third or drain" position, best shown in Fig.4. In said "drain" position of the valve plug 35, the diametrical bore49 therein registers with the delivery port 54 and also with a drainport 6ll.formed in the bottom of the soap receptacle 10. Any watercontained in said receptacl'e drains therefrom through said drain port50, diametrical bore 49 in valve plug 35, and delivery port 54 into thespray tube 56. This drainage of the water from the soap receptacle I0 isinitially enhanced by such air as may be trapped under pressure in theupper portion of the soap chamber 33 in receptacle l0. Subsequently, andwhen this air becomes of the same pressure as that of the atmosphere,air from the outside is admitted into the receptacle chamber 33 throughthe outlet extension 58 so that the drainage from the receptacle maycontinue unimpeded. To provide for the admission of air into theinterior of the receptacle chamber 33, an air ingress port Si is formedin the valve casing 23. This port Bl communicates with the outlet port51 through the longitudinally extending channel in the valve plug 35,said air port 6| being supplied with a valve cage 62 in which ,a ballcheck 63 is contained, said ball check operating to prevent the escapeof air and/or water through said air port 61, but permitting the ingressof air therethrough.

Fixed to the front of valve housing 23 is a plate 64 bearing thedesignations suds, "clear and drain with reference to which the handle44 of the valve plug 35 is turned to supply soapy water or clear waterthrough the spray tube 58. or to drain the soap receptacle through saidtube. Any suitable nozzle may be provided at the end of the spray tube,such as that shown in detail in Fig. 8 and designated by the numeral 65.This nozzle includes a tubular handle 56, in'which the terminal portionof the spray tube 56 is contained, said tube being connected with anipple G1 issuing from a body 68 threaded within said handle 66. A head59 formed with fine spray forming perforations 19 and threaded on thebody 68 clamps a cup-shaped scraper member 11 between it and the end ofsaid handle 66.

When the valve plug 35 is turned into its .suds" position, after thereceptacle has been drained, water from one or the other or both of thebranch feed pipes ll, 12, according to the adjustment of the valves 2|insaid pipes, enters the receptacle through the-feed and inlet ports 52,53, and the diametrical bore 49 in said plug, the air within saidreceptacle chamber 33 being driven out of the same through the spraytube 56 until the level of the water in said receptacle seals theperforations 59 in the tubular outlet extension 58. The

lating in the receptacle chamber 33, being added under the pressure ofthe air trapped in the upper portion of said chamber. Thus, it will beseen that by locating the perforations 59 in the tubular outletextension 58 at an elevation substantially above the bottom of thereceptacle chamber 33, a substantially greater amount of water isprovided within the receptacle for contact with the soap therein thanwouldbe prb-' vided were the outlet from the receptacle chamber to besealed immediately upon the initial influx of water into said chamber.This provision, wherein a substantial quantity of water is at all timessubjected to the soap, contained in the thefspirit of my invention.
